SAFETY 

ELECTRIC SHOCK CAN KILL 

-  Disconnect  the  power  supply  before  working  on 
the welding machine. 
- Do not work with deteriorated cable sheaths. 
- Do not touch bare electrical parts. 
-  Ensure  that  all  the  panels  covering  the  welding 
machine  are  firmly  secured  in  place  when  the 
machine is connected to the mains supply. 
-  Insulate  yourself  from  the  work  bench  and  from 
the  floor  (ground):  use  insulating  footwear  and 
gloves. 
-  Keep  gloves,  footwear,  clothes,  the  work  area 
and this equipment clean and dry. 
 

PRESSURISED  CONTAINERS  CAN  EXPLODE 
IF WELDED. 

When working with a welding machine: 
- do not weld pressurised containers . 
- do not weld in environments containing explosive 
powders or vapours. 
 

THE  RADIATIONS  GENERATED  BY  THE 
WELDING  ARC  CAN  DAMAGE  THE  EYES  AND 
CAUSE BURNING OF THE SKIN. 

- Provide suitable protection for the eyes and body. 

- It is indispensable for contact lens wearers to 
protect  themselves  with  suitable  lenses  and 
masks. 

 

NOISE CAN DAMAGE YOUR HEARING. 

-  Protect  yourself  suitably  to  avoid  hearing 
damage. 
 

FUMES  AND  GASES  CAN  DAMAGE  YOUR 
HEALTH. 

- Keep your head out of the reach of fumes. 
- Provide suitable ventilation of the work area. 
- If  the ventilation is  not  sufficient,  use  an  exhaust 
system that sucks from the bottom. 

 
HEAT,  SPLASHES  OF  MOLTEN  METAL  AND 
SPARKS CAN CAUSE FIRES. 

- Do not weld near inflammable materials. 
-  Avoid  having  any  type  of  fuel  with  you  such  as 
cigarette lighters or matches. 
- The welding arc can cause burns. Keep the tip of 
the  electrode  far  from  your  body  and  from  other 
persons. 

 

PREVENTION OF ELECTRIC SHOCKS  

Take  the  following  precautions  when  working  with 
a welding machine: 
- keep yourself and your clothes clean. 
- do not be in contact with damp or wet parts when 
working with the welding machine. 
-  maintain  suitable  insulation  against  electric 
shock.  If  the  operator  has  to  work  in  a  damp 

environment, he must take extreme care and wear 
insulating footwear and gloves. 
-  check  the  machine  power  cable  frequently:  it 
must be free from damage to the insulation. BARE 
CABLES  ARE  DANGEROUS.  Do  not  use  the 
machine if the power cable is damaged; it must be 
replaced immediately. 
-  if  it  is  necessary  to  open  the  machine,  first 
disconnect  the  power  supply.  Wait  5  minutes  to 
allow  the  capacitors  to  discharge.  Failure  to  take 
this  precaution  may  expose  the  operator  to 
dangerous risks of electric shock. 
-  never  work  with  the  welding  machine  if  the 
protective cover is not in place. 
-  ensure  that  the  earth  connection  of  the  power 
supply cable is perfectly efficient. 
This  machine  has  been  designed  for  use  in  a 
professional  and  industrial  environment.  For  other 
types  of  application  contact  the  manufacturer.  If 

electromagnetic disturbances 

are found it is the 

responsibility  of  the  machine  user  to  solve  the 
problem  with  the  technical  assistance  of  the 
manufacturer. 

It is forbidden for people with PACEMAKERS to 
use or come near the machine. 

 

 

 

 
PREVENTION OF BURNS  

To  protect  your  eyes  and  skin  from  burns  and 
ultraviolet rays: 
- wear dark glasses. Wear suitable clothing, gloves 
and footwear. 
- use  masks  with  closed  sides,  having  lenses  and 
protective glass according to standards (degree of 
protection DIN 10). 
-  warn  people  in  the  vicinity  not  to  look  directly  at 
the arc. 

 
PREVENTION OF FIRE 

Welding produces splashes of molten metal.
